SPECIFICATION forming part of Letters Patent No. 593,016, dated November2, 1897.

Application filed May 22, 1896 Serial No. 592,645. (No modeld To (LZZwhom it may concern.-

Be it known that I, GEORGE HAVELL, a citizen of the United States,residing at Newark, county of Essex, State of New Jersey, have inventedcertain new and useful Improvements in Bicycle-Lamps, fully describedand represented in the following specification and the accompanyingdrawings, forming a part of the same.

The object of the present invention is to reduce the number ofpieces,and thus to cheapen the constructionof a bicycle-lamp formed ofsheet metal. To accomplish this object, I form the body with a centralglobe having a collar at the bottom to attach the oil-cup and a flaringfunnel at the top, and I form such body wholly of two pieces by dividingthe body in the process of manufacture vertically upon the center lineof the collar and funnel. By this construction the opposite halves maybe struck in the same die, as the height of the globe, funnel, andcollar is obviously the same upon each of the halves, and the centralportion of the globe is easily perforated upon one of the two parts toform the aperture upon which the lens is secured. Such aperture isformed by stamping a circular piece or segment from the middle of theglobe upon one of the parts, a bead being then turned upon the edge ofthe aperture to strengthen the same and form a means of attachment forthe lens-ring. By forming the aperture and the bead wholly on one of theparts I make the bead integral throughout its entire periphery, and thusmake it much smoother and stronger than if it were divided by a verticalor horizontal joint.

In dividing the lamp-body at the opposite sides I intersect the bezelsin which the sidelight jewels are secured, and I therefore form each ofthe body parts with a half-collar having a semiseries of tonguesattached thereto, the collars and tongues, when the two parts of thebody are united, serving, respectively, to support the back of the bezeland to bend over the front of the same. With this construction each halfof the body, including the bezels, is readily stamped from a singleblank of suitable form. p The invention will be understood by referenceto the annexed drawings, in which- Figure 1 is a side view of thebicycle-lamp with the lens and its collar in section. Fig. 2 is a frontview of the lamp-body and oil-cup with the body in section upon line 2 2in Fig. 1 and the jewel omitted from the righthand bezel. Fig. 3 is aplan of the oil-cup with the collar upon the body in section and shownin solid black. Fig. at is a plan of the socket upon the top of theoil-cup to receive. the collar B B. Fig.5 is a perspective view of theband which forms the catch for the oil-cup. Fig. 6 is a section of thebody on line 6 6 in Figs. 1 and 2, showing the shape of the flanges uponthe two parts of the body to form the vertical front seam; and Fig. 7 isa similar section with the seam closed. Fig. 8 is a view of the innerside of the ring for the lens. Fig. 9 is a plan of the funnel-cap. Fig.10 is a plan of the top of the funnel, and Fig. 11 is a cross-section ofthe collar at the bottom of the body with vertical folded seam like thatshown in Fig. 7.

A A design ate the front and rear halves of the body.

B B are the two halves of a collar, formed integral with the'body at itslower end to receive'the oil-cup.

G O are the two halves of the funnel, formed integral with the body atits upper end. The front and rear parts of the body are shown in Fig. 6provided, respectively, with the bent flange a and the straight flangeta which, as they form a straight joint between the two parts of thebody, can be simultaneously closed in a single pressing operation toform the vertical standing seam a. Such standing seam can be readilyformed (without supporting the parts intern ally) by dies adapted tofold the flange a over the flange a as is clearly shown in Fig. 11. Bysuch method of closing the joint I avoid the necessity of supporting theparts internally, although I am able to produce thus only a seam whichpro jects radially from the body throughout the entire length of thejoint; but such radiallyprojecting seam is especially adapted to form arib upon opposite sides of the supportingcollar 13 B, which, whennotched, cooperates with a catch upon the socket of the oil-cup. Theseam is shown intersected upon the middle of the body by the bezel,which is formed integral with the sheet metal of the body, the parts A Abeing .formed each with a semicollar (9 and with a semiseries of tongues1), (shown at the right-hand side'of Fig. 2,) the collar and tonguesbeing adapted to support edge of the aperture and provided upon opposite sides with notches 'e,.and the lens F is shown secured in acollar f, having an annular recess f to fit over the bead e and twotongues f which engage the back of the bead, except when turned oppositethe notches .6, to detach the lens and collar in the usual,

The seams upon opposite sides of the col- 1 lar B 13 form vertical ribs,which are provided with n otches a to cooperate with a catch upon theoil-cup. To furnish such a catch, the oilcup is provided with a socketE, attached to the top of the oil-cup by a flange D, soldered thereto,and is furnished upon the opposite sides with loops E, adapted to fitover the notched ribs a, The loops E are formed with notches E (markedat the left side of Fig. 2,) corresponding with the notches a in theribs, and a band g of the same width as the notches is fitted to theexterior of the socket E and provided with loops g, which correspond ex-The top C and tube c are formed. integral with the funnel O 0, so thateach half of the lamp-body is in one piece from the I The band is formedwith a thumb-piece t to rotate it upon the socket and with a stoppin h,which projects above and below one of the loops 9 to contact with theloops E when the loops are coincident, as shown in the dotted lines hand 2 upon the lower side of Fig.

The stop it and the thumb-piece t' are shown in full lines upon theupper side of Fig. 3, indicating the position in which the band isturned to lock the oil-cup to the collar B B by shifting the cylindricalor body portion of the band g into the notches a, as shown in Fig. 2.When thus shifted, the band fits between the upper and lower portions ofthe loops E and is thus held from displacement,

and it is also held in place at other portions of its periphery by teetht, stamped outwardly from the metal of the socket at the upper and loweredges of the band. The collar B B is V 5 formed with a notch j to passover the spindle The funnel is flared or expanded toward? the top 0 tofurnish area around its outer: edge fora sufficient number of vent-holesc. (Shown in Fig. 10.) The top is furnished; with a central tube 0,projected upward to support the cap, which is provided with a;- roundflat seat d in the center to rest upon is, which is used for adjustingthe lamp-wick, and the top of the socket is cutout for one quadrant ofits periphery, as shown in Figs. 1 and 2, down to the top of the band 9to permit a partial rotation of the wick-tube and its clamping deviceswith the spindle 7t to detach the wick-tube from the oil-cup whennecessary to fill the cup with oil.

It will be observed by comparing the position of the thumbpiece t' infull lines and dotted lines in Fig. 3 that the band may bee 1 turnednearly a semirotation upon the socket The seat 61 has a cylindricalborder d from which a bell d is projected downward, anda series of holes0 (shown in Fig. 9) is formed?

E'when locking the oil-cup to the lamp-body, and such an extendedmovement of the catch wholly precludes the possibility of an accidentaldisplacement or disengagement of the catch, and the oil-cup is thusfastened to the lamp-body most securely.

A sliding catch adapted to engage the notched ribs upon the collarof thelamp-body is much more durable and presents ilarger wearing-surfacesthan the spring-catches, which snap into a hole or against a shoulderautomatically and which depend chiefly upon the resilience of the springfor. their engagement. I have therefore claimed a sliding catch forengaging with such notched rib.

By dividing the body into opposite halves vertically and connecting theparts by a folded scam the seam furnishes a convenient rib upon thecollar at the bottom to constitute a portion of the locking device.

I hereby disclaim the application filedJuly 18,, 1896, with Serial No.599,598, by G. I-Iavell and A. H. Meyer for patent on bicycle-lamps, anddo not claim, broadly, the bead, (lettered e in my drawings,) as thesame is shown and claimed in the said application.

. Having thus set forth the nature of my invention, what I claim hereinis- 1. A bicycle-lamp having aglobe, with funnel upon the top andoil-cup uponthe bottom, and divided vertically upon the center line,with the two parts formed of .sheet metal and united by a verticalstandingseam projected radially from the exterior of the joint, and theseam notched transversely at the opposite sides of the collar to engagea lock upon the oil-cup, as and for the purpose set forth.

2. In a bicycle-lamp, the combination, with the globe A, A, and thecollar B, B provided with the notched ribs a at the opposite sides, ofthe oil-cup D carrying the socket E to'fit the collar and provided Withnotched loops E to fit over said ribs, and a sliding catch movable uponthe socket in the notches of the loops to engage the notches in theribs, as and for the purpose setforth.

3. In a bicycle-lamp, the combination of a collar at the bottom providedwith notched ribs at opposite sides, an oil-cup having a socket to fitthe collar and provided with notched loops to fit over the said ribs,and an annular band fitted to rotate in the notches of the said loopsand provided with corre sponding' loops, and with means for rotating theband to look the socket upon the collar, substantially as herein setforth.

In a bicycle-lamp, the combination, with the globe'A, A, and collar B Bprovided with the notched ribs a at opposite sides, of the funnel havingthe integral top (J curved in- Wardly and provided with the central tube0, of the cap having the flat seat d fitted to the top of such tube andprovided with the bell d extended downward over the cover, and the capand cover being perforated, as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses. o
